If you put the axes origin at {0, 0} it is difficult to read the labels. S11Exercise64b = {{0, 120}, {10, 119}, {20, 118}, {30, 117}, {40, 116}, {50, 115}, {60, 114}, {70, 113}, {80, 112}}; ListPlot[S11Exercise64b, PlotStyle -> {Blue, AbsolutePointSize[6]}, FrameLabel -> {x, y}, Frame -> True, Axes -> False, PlotRange -> {{-4, 98}, {111, 121}}, Epilog -> { Text[Style[#, 12], #, {-1.25, 0}] & /@ S11Exercise64b}] Graphics[{ Text[Style[#, 12], #, {-1.25, 0}] & /@ S11Exercise64b, Blue, AbsolutePointSize[6], Point[S11Exercise64b]}, FrameLabel -> {x, y}, Frame -> True, PlotRange -> {{-4, 98}, {111, 121}}, AspectRatio -> 1/GoldenRatio] Bob Hanlon On Wed, Jul 4, 2012 at 3:29 AM, Mike McCraith <sandwaterhand at gmail.com> wrote: > > Hello there.
